## Background
FIELD OF INVENTION
As a new industrial product, the present invention concerns, on the one hand, a toilet device of the commode type, consisting of a box and of a collection bag, produced and assembled from a flat, pre-cut cardboard blank without the use of an adhesive, of adhesive tape or of staples. It likewise concerns the use of the said toilet for the elimination of mephitic odours.
PRIOR ART
It is known that during their outdoor activities, schoolchildren visiting the countryside as a group are in the habit (1) of relieving themselves against trees, or in copses and (2) to leave their waste (urine, faeces and pieces of wiping paper) on the ground. It is likewise known that during exercises, or during operations, troops of soldiers are in the habit (1) of digging trenches to receive their waste and (2) of covering the trench with soil before breaking camp. In either case there is a major risk of contaminating the soil, especially by strains of Staphylococcus aureus, or (more seriously) of Staphyloccocus faecalis, which are liable to infect both humans and animals.
It is particularly difficult to transport chemical WC cabins, which are heavy and cumbersome, in order to deal with calls of nature of children and/or of adults during trips to the countryside.
In order to deal with this problem, consideration was given to the use of pre-cut blanks to assemble on the spot simple boxes, each of whose upper, lower and side walls would consist of a single panel and which would be provided with an opening in the upper wall in which it would be possible to accommodate a bag for the collection of waste (urine, faeces and paper). Nevertheless, many boxes of this type are not suitable, such as, for example,
the so-called American box, which consists of a top and two caps, which calls for the transport of adhesive for fastening the caps to the top
the so-called “filing” box, which comprises an enclosure with four flaps, which interlock at the moment of being used and a cap, which becomes irreversibly deformed under the weight of an adult.
There is also European Patent EP 0 948 304 B, which mentions a single use waste collection bag, which is impervious and contains a gelling agent which swells by the absorption of the water present in the waste, to (1) coat a bedpan provided for sick, bedridden and handicapped persons and to (2) close the collection bag containing the waste of a patient by means of at least one sliding tie (i.e. a tightening cord) located in a hem running along the opening of the said bag, and then to tie (i.e. to make several turns and at least one knot with the said tie under the upper part of the bag and above the absorbed or coated waste), to (3) extract the said bag from the bedpan without its having become contaminated and then to (4) proceed to the normal incineration of the used bag. The bedpan collection bags complying with the said patent EP 0 948 304 B are greatly appreciated by hospital personnel.
The ideal would be to have flat blanks to assemble on the spot (i) equipped with such impervious bags containing the said gelling agent as referred to in the aforementioned EP 0 948 304 B and (ii) able to withstand the weight of users without having to transport or use adhesives or adhesive tape with its reel (where the mass of the adhesive is very heavy and where specialists refer to “aggressively adhesive” adhesive mass), or staples and their staple gun.
PURPOSE OF THE INVENTION
The invention concerns a new technical solution for dealing with the aforementioned problems and for providing as far as possible an ideal product. This objective is met by providing a box, possessing as a result of folding and consolidation
an opening in its upper part to receive a collection bag

BRIEF DESCRIPTION OF THE DRAWINGS
In the appended drawings
FIG. 1 shows a flat blank according to the invention, to be assembled and consolidated into a device according to the invention
FIG. 2 is a perspective view of a commode according to the invention



DETAILED DESCRIPTION OF THE INVENTION
Panel (1) of the device according to the invention, which serves as a seat, is polygonal, has an even number 2n of sides and the vertical axis of symmetry is the axis of the box, n being a whole number equal to or greater than 2 and having, in particular, the value of 2, 3 or 4; the preferred value being accordingly n=2, the said panel (1) being a rectangle or better still, a square.
Moreover, the said panel 1 which serves as a seat, is connected to at least two series, each consisting of n+1 panels, namely
to a first series of panels (10, 11, 12) along a folding rib (80) through a panel (11) located between panel n° 1 (10) and n° n+1 (12) and
at least a second series of panels (10a, 11a, 12a) analogous to the first series and angularly offset from the latter by an angle 2π/n, the said angle being π/2 (where n=4), 2π/3 (where n=3) or π (where n=2).
The number of double sidewalls advantageously goes from 2 (where n=2) to n (where n is greater than 2) and the said double walls are formed by consolidating the first panel (10) of one series with the last panel (12a) of the series which angularly follows.
According to a preferred embodiment, the device according to the invention is characterised by the fact that panel (1) which serves as a seat, is rectangular, or better still, square (n=2), is connected to the said first series of panels comprising three side panels (10, 11, 12) by means of a fold (80) attaching it to the central panel (11) of the said first series and to the second series opposite (10a, 11a, 12a), angularly offset by an angle π via a fold (80a) connecting it to the centre panel (11a) of the said second series, the double side walls being formed by the consolidation of the pair of the outermost side panels (10, 12a, 10a, 12)
In the first series of three side panels (10, 11, 12) the centre panel (12) is connected to panel (1) which serves as a seat via the folding rib (80). It is this centre panel (11), which makes it possible to connect the first series to the said panel (1), since the said panel (11) is also connected to one of the outermost panels (10) by the folding rib (8) and to the other (12) by the folding rib (82).
In the second series of side panels (10a, 11a, 12a), the centre panel (11a) is arranged analogously. It is connected to panels (1, 10a and respectively to 12a) by means of folding ribs (80a, 81 and respectively 82a)
The device according to the invention may also comprise a cover consisting of a panel (5) connected via a horizontal folding rib (90) to panel (1) serving as a seat and comprising at least one extension foot (4, 4a), which is destined when the said cover is closed, to enter perpendicularly into a corresponding slot (3, 3a) provided in the said panel (1) which serves as a seat.
If necessary, it is possible to provide on at least one of the first and second series of side panels, flaps (30, 31) in order to improve the resistance of the box to the weight of users. In FIG. 1, a first flap (30) is connected to the outermost panel (12a) by a folding rib and a second flap (31) is connected to the outermost panel (10a) of the second series of panels.
The V slots (70 and respectively 71) whose apices are arranged on the folding ribs (81 and respectively 82) and the branches, are deployed obliquely upwards in the direction of panel (1) serving alongside the half-V slots (70a and respectively 71a) provided in the vicinity of the edges (91 and respectively 91a) of the outermost panels (12 and respectively 12a) for fastening the collection bag (not shown) to the commode in such a way that it covers at the top the whole of panel (1) serving as a seat. The collection bag whose bottom is lodged in the internal cavity of the commode by its opening (2) is consolidated at the moment of the use of the said box by means of the aforementioned sliding connection which is lodged in a hem or a belt running the entire length of the open top of the said bag. It is this sliding connection, which enters into the slots (70, 70a, 71, 71a).
The single-use collection bag, which is impervious to gases and liquids, is made of plastic or of a composite material where the outside is of paper or of a woven or non-woven fabric and the inside of plastic and the said bag contains a gelling agent which swells on contact with water in urine or faeces to absorb the said urine and to coat the said faeces. The gelling agent may be a polyacrylate, as stated in the aforementioned EP 0 948 304 B, or it may consist of particles of polyurethane, or of finely divided colloidal silica. The advantage of particles of finely divided colloidal silica resides in the fact that they possess a deodorant effect. The deodorant effect of charcoal is however greater than that of the said silica particles.
The device according to the invention is particularly useful (i) for groups of schoolchildren, or of soldiers going to places where there are no clean WC's and (ii) for building site personnel. When travel is required, one transports one or more flat cardboard blanks and a quantity of collection bags statistically adequate for the duration and for the number of persons who may require them are transported and one or more commodes are assembled.
After use, it is sufficient to close the open top of the bag using the sliding closure and to roll it up, making at least one knot. The bag is then dropped into the inside cavity of the box, because there are no mephitic odours, particularly if a deodorant has been added to the gelling agent. Lastly, the box and its contents are incinerated the same evening, or the following day.
